Lonely Planet author Greg Brown said that spiders are a "staple" food in the country.
He claimed this foodstuff is "not half bad" if it is "fried until crispy", while they also have a high content of important minerals, such as iron.
A number of insects are consumed in Cambodia, including honeybee larvae, beetles and crickets, the specialist continued.
Mr Bloom noted that many meals in the county have equivalents in Thailand or Vietnam and he advised people to try the Amok, the country's "national dish".
This is a fish in a banana leaf that has been steamed with coconut milk, lemongrass and savoury spices.
According to Lonely Planet, there is an old Khmer saying regarding food: "Eat anything that has four legs except a table, eat anything that flies except an aeroplane and eat anything that travels by twos apart from a bicycle."
